DEVICE FOR CLEANING NAILS AND TACKS.

SPECIFICATION forming part of Letters Patent No. 294,440, dated March 4,1884.

Application filed October 30,1883. (No model.)

To aZZ whom it may concern.

Be it known that I, HARVEY B. Grams, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Apparatus for Cleaning Nails and Tacks, of which thefollow-. ing is a full, clear, and exact description, ref erence beinghad to-the accompanying drawings, making a part of this specification,in which- 1 Figure 1 is a vertical section of a nail and tack cleanerwith my improvements attached. Fig. '2 is a front elevation of the same.Fig. 3 is a detail to be referred to.

My present invention relates to apparatus for cleaning and separatingnails and tacks and similar articles from scale and other foreignsubstances,- and it consists in the combination of devices hereinafterexplained and claimed.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have carried it out.

It is peculiarly difficult to separate nails and tacks from certainmaterials that become associated with them during manipulation,especially during the process of tinning. The usual appliances leavethem after the coating has been accomplished associated with tinflakesof all sizes and shapes and. every degree of fineness. ,7 The object ofmy present machine is to remove these foreign substances.- In thedrawings, A represents a vertical vessel or chamber, inwhich are placedseveral inclined planes B B B", shown 'in Fig. 1. The materials to becleaned, entering the top of the vessel A and descending over the slopesor inclined planes B B B, are cooled, and are o partially arrested attheir fall from plane B by a bridge, 0, which stops their impetusdownward, and they fall gently into the sloping and vibrating chute G,which is fixed loosely at its lower end, while the upper end rests on atransverse bar, D, pivoted at its center, and one end of which is givena limited but rapid vibrating movement by the pitman E and crank F,as-shown in Fig. 2, and operated by any of the well-known mechanisms.

The effect of this vibrating motion on the material is. to dance itsparts in all positions rela tive to a blast of air projected under theregulation of a valve at approximately a horizontal direction from thefan-shaped'blast-nozzle G,-as shown in Fig; 3. By this shaking up,caused by the rapid vibration of the chute and the inclination of thechute itself, the nails and tacks acted on move down the slope while thetin-flakes, danced into favorable positions,

combination with the vibrating chute O and an air-blast nozzle, G, allconstructed to operate substantially as and for the purpose described. Y
